This subsystem is intended for use when rendering in a shipping game (but can also be used in PIE during development/testing). SeeUMoviePipelineQueueSubsystemfor the Editor-only queue which is bound to the Movie Render Queue UI. To do simple renders at runtime, call AllocateJob(...) with the Level Sequence you want to render, then call FindOrAddSettingByClass on the job to add the settings (such as render pass, output type, and output directory) that you want for the job. Finally, call RenderJob with the job you just configured. Register a delegate to OnRenderFinished to be notified when the render finished. You can optionally call SetConfiguration(...) before RenderJob to configure some advanced options.
